(Illustrated. ) In the accompanying illustrations, we show the improved type of Crompton’s atmospheric silent ash hoist The ma- chine was, designed by a practical marine engineer, whose early training at sea and the experience then gained by the methods and means of raising ashes from the stokeholds of steamships that happened to be in vogue, has resulted in the production of an ash hoist that is sure to find favor. It is claimed that with the apparatus under notice all the trouble and annoyance formerly felt as to notse, etc., is overcome. The tubes of the hoist are made of steel 5% in. diameter. The inner tube is of copper, which forms a lining very ingeniously secured to the steel tubes and hy- draulic jointed in lengths to conform to whatever required lift may be desired for each ship. The piston with a flexi- ble cup valve, works in this tube, and to this is secured the steel rope which is taken over the swivel head to the ven- tilators, and again over the usual pulley fixed in the ven- tiators, and so on to the stokehold plates from which ashes have to be raised. At the bottom of the hoist tubes is fixed a connection having a port-way opening to the bot- tom side of the piston. In this bottom piece is screwed a 14 in. wrought-iron stiction pipe (as shown in the illus- tration), at the top end of which is screwed on the instru- ment which gives all the power and action of the machine, and is composed of a combination compound cock, an air extractor, a I in. steam cock (asbestos packed), and a 2 in. exhaust cock, having a side branch for connection to the main cofidensers. These various connections are al- luded to in the following references:—S, connect to main and donkey boilers; C, connect to main condenser (va- cuum) ; and E, lead to waste steam pipe, or into the fun- All the stoker has to do is to move the operating handle one- eighth of a turn; this admits steam through the compound cock to the air extractor and at the same time opens up communication with the bottom side of the piston in the tube. A powerful vacuum is at once formed, and the pres- sure of the atmosphere acting on the top side of the piston through the small air holes in the swivel head, the piston “immediately descends and the wire rope with it, which be- ing hooked on at the other end either to bags or buckets of ashes, it naturally follows that these must be raised up the ventilators, and no matter at whatever position of travel the piston is stopped at, the loaded bags or buckets remain quite safe and stationary, and can only be lowered by moving the operating handle one-quarter of a turn back- wards, which at once cuts off the steam and at the same time admits a sufficient quantity of air to the bottom side. of the piston to destroy the vacuum existing. It will be at once seen that to overwind the ash bags or puckets be- THE MARINE RECORD. comes a matter of impossibility; there is nothing to give way, break down, or get out of order.

The machine under these conditions costs practically nothing to work at sea, a matter deserving of great consideration that should commend it- self to shipowners. A prominent superintendent engineer of a line of steamers having every ship fitted with the hoists testifies that the piston cup valve which works in the tube lasts over six months; and, as the cost of each valve is but 50 cents, it practically means that the upkeep cost does not exceed $1.00 per annum, which the makers guarantee with every machine turned out.

Booth, of Chicago, is out at last in an elaborate series of denials concerning matters and things touching the lake fish trust. He denies that the $5,000,000 company is a com- bination; he denies that it is in any sense a trust; he denies that the company has retained $2,500,000 of the stock to catch foreign investors. He says the company is engaged in the beneficent business of regulating the supply and dis- tribution of fish. He further adds: ‘It would be practically impossible to form a fish trust, however, because every man who is so disposed can go to the lakes or the sea and fish and sell the product of his labor to the best advantage.’’ Mr. Booth also said that one of the reasons why the A. Booth Packing Co., Chicago, bought up the fish houses in the country was to distribute the fish so that all the markets would be adequately supplied. Heretofore this has not been the case. One market would receive twice as much as it would sell while another would not get half enough. The monopolistic Booth Co., head of the fish trust, simply desire to corral the lake food product, and this they are likely to do through the combination they have organized. = oor THE object in covering steam pipes is to save fuel by pre- venting waste of heat and condensation of steam while being conveyed from boiler to engine, pump, or point of utiliza- tion. The saving is effected by covering the boiler, domes, steam pipes, etc. The Standard Pipe Covering Co., Cleve- land,are manufacturers of asbestos air-cell sectional covering which protects the surface of the boiler, pipes, etc., from influence of the atmosphere, thus preventlng the heat of the steam from being abstracted, but, instead, delivering it dry and without loss to point of utilization. Pipe covering is no luxury, but an actual necessity. This covering is entirely composed of corrugated asbestos paper, with canvas jacket, making it the most durable sectional covering on the market, and one that cannot be injured by any vehicle sub- stance in contact with it.
